CHARLES B. SINGLETON, OF LA. GRANGE, FLORIDA, ASSIGNOBJ v013 ONE-THIRD TBYRON AQBEAL, or NEW YORK, N. Y., AND ONE-THIRD vilain, :FLORIDA s To,THOMAS A.coNwAY, or TI'rUs- ROTARY rLow Appnation sied :une 12,1929.serieu No. 370,365.

The present invention contemplates thel provision of a rotary plow whichis simple in construction, and very efficient for 4the purpose intended,the invention residing in the :onstr'uctiom combination and arrangementof parts hereinafter claimed.y .l

InV the drawings forming part of this application like numerals ofreferenceindicate similar parts in the several views, Vand .vherein Y fFigure 1 is a side 'elevation partly in section illustrating theinvention. Y

Figure 2 is a top plan view.

Referring to the drawings in detail, 10

'.epresents the side membersofa substantially V-shape frame terminatingto provide straight parallel portions 11 upon which are pivotallymounted a pair of bracket arms 12 inwhichthe axle 13 is mounted.

The plow proper preferably. consists of a plurality of spaced disks 14Vwhich are mounted on the axle 13, and each disk is formed to provideacircumferential series of curved hngers 15 as clearly illustrated inFigure l. Jiny number of such'disks'may be used in a single plowconstruction, while each disk may vary in the number of fingers formedthereon, depending of course upon the character of work to be performed.Ylilachjfinger 15 assists in supporting a cutting blade 16,

and the correspondingfingers ofthe respec# tive disks are slightlyoffset so that the particular blade connecting the same is arrangedapproximately at that the cutting edge of each blade is indicated at 17and separate from the blade itself so that it kcan be convenientlyremoved lfor finger kwith which it is associated. OneA of arms 12 whichsupport'th'e axle 18 is formed with an angular extension 18 which 4isconnected with one end ofa rod 19,

the'other end of which is connected with a lever20 through-theinstrumentality of which an angle of f It-will, lso be noted uponinspectionof'Figure Y1 edge of eachterminates slightly in` theplow initsentirely can be raised orv lowered with lrelation to the ground. Alsosupportedupon the frame in advance of the plow is a suitable fender orguard 21. 'n

' It 'is of course to be understood that the plow can be rotated by anysuitable means, but I have vherein shown the plow used in conjunctionwith a tractor, the axle of which is indicated at 22. "The side'members10 of' the frame are supported by the axle 22 as illustrated inFigure`2. while the plow is rotated from a transmission drive shaft in-Y j cluding thesections 23 and 24 which are connected by a universaljoint 25. The section 24 is provided with a bevel gear 26 whichmesheswith a similar gear 27 carried by the adjacent end ofthe axle 13,while these gears and drive shaftare arranged in a suitable Vhousing 28.As above stated theV plow can be quickly and conveniently `raised orlowered with relation to the ground, and will revolve about sixhundred'revolutions per min-k ute. The speedV however, can be vvariedasthe occasion requires by shifting the gears of the tractor. I y s Whileit is believed that from the forego,- ing descriptionthe nature andadvantages of the invention will be readily understood, I desirel tohave it kno-wn that I -do not limit myself to what is herein shown anddescribed and that such changes may be resorted Vto when desired as fallwithin the scope of what is claimed. l

VVhatI claim is: y f

A vrotary cutting toolcomprising an axle, spaced disks mounted thereon,each disk including a circumferential series of curved lingersterminating in pointed extremities, a

' shoulder formed/oneach `finger rearwardly of the said extremity,cutting blades connecting the corresponding fingers of the respectivedisks and curved to conform to the curvature of said fingers, eachvblade contacting theshoulders of said corresponding fingers and lyinsubstantially iiush with the .outer surface t ereof, and the cuttingedge of'each blade projecting a slight distance beyond *Y the freeextremities of said fingers..

kIn testimony whereofy I aix my signature.
